This invention relates to wrapping machines, and to wrapping methods,and mpre particularly -to a machine for wrapping coins to facilitate thehandling of come in banks or elsewhere.

A more particular object is to provide a coin wrapping machine whichwill be simple in construction, rapid, accurate and efficient inoperation, and inexpensive to manufacture. a

A further object is to provide an improved method of securely wrapping astack of coins in such manner that the coins at the ends of the stackwill be exposed suificiently to show the denomination thereof.

With the above and other objects in View, the invention consists in thenovel and useful provision, formation, combination, association andrelative arrangement. of parts, members and features, all as hereinafterdescribed, shown in the drawings, and finally pointed out in claims.

Qorresponding parts in all the figures are deslgnated by the samereference characters.

Referring with particularity to the drawings, I have shown certaindevices and elements which may be used with my wrapping mechanlsm suchas a sorting mechanism S, a counting mechanism C and a wrappingmechanism W for each denomination of coins to be wrapped; there beingfour of such units shown in the present embodiment in'Fig. 1, forrespectively sortlng, counting and wrapping pennies, dimes, nickles andquarters, which units are respectively indicated P, D, N and Q.

Furthermore I have included a coin hopper H, a coin chute I inclineddownwardly from said hopper, a coin feed mechanism F between said hopperand said chute, and four coin stacking tubes d, p, n and q, leadingvertically downwardly from the chute I to the sorting mechanisms S ofthe units D, P, N and Q respectively, there being openings d, p, and nin the bottom of the chute which lead into the upper ends of the tubesd, p and n respectively while the lower end of the chute leads into theupper end of the stacking tube 9. The stacking tubes are provided withlongitudinal slots (2 17 n and g for observing the coins in said Thechute I is formed with four superimposed coin guideways 1, 2, 3 and 4for respectively guiding the dimes, pennies, nickles and quarters intothe stacking tubes d, p, n and g. The guideway 1 is of a width toreceive only a dime and the bottom 1- thereof is below the guideways 2,3, and 4, and the guideway 1 leads downwardly to the opening d, throughwhich opening dimes are discharged from said guideway into the dimestacking tube d. The guideway 2 is of a width to receive pennies and thesupporting faces 2 thereof are above the bottom 1 of the guideway 1 andbelow the guideways 3 and l, and said faces lead downwardly into theopening p through which the pennies are discharged from the guidewayinto the penny stacking tube 1. The guide-way 3 isof a width to receivenickles and its supporting faces 3 are above the supporting faces 2 ofpenny guideway 2 and the supporting faces 3 lead down wardly into theopening a through which the nickles fall from the guidcway 3 into thenickle stacking tube '22. The guideway 4 is of a width to receivequarters. and its supporting faces 1 are above the faces 3 of guideway3, and the supporting faces 1 lead downwardly through the lower end ofthe chute into the quarter stacking tube 9 into which the quarters dropfrom the guideway.

The coin feeding mechanism F includes a pair of feed rollers f and f,and gears 5, 6 and 7 through which said rollers are driven in the samedirection. The rollers 7' and f are journaled in bearings 8 and 9 atthelower discharge end of the hopper H with the periphery of the roller fflush with the inner side of the rear inclined wall h of said hopper,and with the periphery of the roller f spaced slightly forwardly fromthe periphery of the roller 7 at a distance slightly greater than thethickness of the largest coin handled by the machine, so that the coinsmay pass between said rollers one by one only. The roller 7' is mountedoutside the hopper with a portion of its periphery projecting through anopening it in the inclined wall it of the hopper H so that the peripheryof said roller rotates flush with the inner side of said wall 71. Theroller f is mounted half within the lower end of the hopper andholds'all the coins in the hop per except those passing out one by onebetween the rollers f and f. The gear 5 is secured on a power shaft 10between and in mesh with the gears 6 and 7 which are secured on thejournals (5 and 7 respectively of the rollers f and f. The rotation ofthe gears 6 and 7 by the gear 5 rotates the rollers f and 7" bothcounter clockwise. but the adjacent peripheral surfaces of said rollerswithin the hopper are rotated in opposite directions so that theperipheral surface of the roller f within the hopper will traveldownwardly and feed the coins in the back of the hopper one by onebetween the rollers into the chute I, while the peripheral surface ofthe roller f within the hopper H travels upwardly and pushes all thecoins back into the hopper, except those fed out by the roller 7.

The sorting mechanism of each unit comprises a slide 8 constructed witha, lower horizontal plate 11, an upper horizontal plate 12 and avertical cylindrical sorting barrel B secured at its lower and upperends to the forward ends of said plates 11 and 12 respectively with thebore of the barrel extending through said plates. The slide .9 ismounted in a slideway s which consists of a flat plate 13 with its sideedges 11 turned upwardly and inwardly. The slide plate 11 rests andslides upon the slide-way plate 13 with the side edges of the plate 11fitting and sliding in the channels within the upwardly inturned edges14 of the plate 13. The slide-way s is provided with an opening 15 inits forward end. Normally the slide S rests in a position with itsbarrel B directly under a coin stacking tube such as tube q. (See Fig.2.) The barrel B is of such height as to hold a predetermined number ofcoins.

Each counting mechanism compris s a register R with its operating arm rconnected to one end of a link 16 which is hooked at its other end intoa side slide plate 12 at 16.

The wrapping mechanism TV comprises primarily a plurality of verticalwrapping rollers 'w, 'w', 10 and 10 spaced apart in a circle, and a pairof crimpers 7c and 7c. The wrapping rollers are preferably made of steelwith knurled surfaces 17. The rollers w, 'w. w and 10 have lowerjournals 20, 21 and 22, and a shaft 23 respectively connected to theirlower ends, and said rollers have upper journals 24. 25, 26 and 27respectively. The lower journals 20 to 22 inclusive, and shaft 23,extend through short radial slots 30 in a lower plate 31, on which platerest the lower ends of the wrapping rollers w, w, 20 and L0 An upperplate 32 is fixed on the lower end of a vertical cylindrical throat 33and a cam disk 34 is j ournaled on said throat and rests upon the saidupper plate. The upper plate 32 is provided with radial slots 35 and thecam disk 34 is provided with a plurality of cam slots 36 which extendover the slots 35 respectively. Each of the upper journals 24 to 27inclusive, extends upwardly through a pair of slots 35 and 36 in theupper plate and cam disk respectively. The upper end of the throat 33 isfitted in the opening 15 of a slide-way s. The cam disk 34: is formedwith an outwardly extending arm 37, to which is connected one end of aspring 38, the other end of which spring is connected to a stud 39 onthe upper plate 32, so that the spring normally holds the caln disk inposition with the rear ends of its slots engaging the upper journals 24to 27 inclusive and holding the upper ends of the Wrapping rollers w, w,'w and w in their innermost position. On the lower and upper ends of thewrapping roller w are secured the crimpers k and k respectively, whichconsist of metal disks 40 of slightly larger diameter than the roller w,which disks are formed in their crimping faces with a plurality ofspaced radial grooves 41. Between the wrapping rollers 'w and 'w arelocated a pair of spaced vertical guides 42 and 43, providing anentrance space 44 there-between through which the coin wraper isintroduced. A guide 45 is located etween the rollers 'w and 'w. A guide46 is located between the rollers w and 10 A guide finger 47 is locatedbetween the rollers 'w and w A U-shaped wrapper guide 50 is provided forguiding the wrapper through the space 44 into the wrapping mechanism,Onthe lower journals 20, 21 and 22 and on the shaft 23, immediatelybelow the lower plate 31 are respectively secured pinions 51,

r 52, 53 and 54 which mesh with a gear 55 secured on a sleeve 56journaled at its upper end in a conical bearing 57 in the lower plate31. A plunger 58 extends through the sleeve 56 and has a head 59 on itsupper end above the plate 31 between the rollers w, 'w, w and Q0 On thelower journals 20, 21 and 22 and on the shaft 23 immediately below thepinions 51, 52, 53 and 54 respectively are secured pulleys 60, 61, 62and 63 over which extend a coil spring belt 64 which yieldingly holdsthe lower ends of the rollers w, w, w and 'w in their innermostposition.

On a power shaft are secured cams 71, 72 and 73 and a bevel gear 74. Thebevel gear 74 meshes with a bevel pinion 75 on the lower end of theshaft 23 whereby said shaft is rotated. The cam 71 is engaged by thelower end of a lever 76, the upper end of which is connected to one endof a rod 77 which in turn is connected at its other end to the slide 8as at 78. The cam 72 is engaged by the lower end of a lever 79, theupper end of which lever engages the cam disk arm 37. The cam 73 isengaged by a lever 80, one end of which engages the lower end of theplunger 58 while its other end is connected to one end of aspring 81which in turnis connected at its other end to a fixed part 82.

The operation is as follows: The coins to be sorted, counted and wrappedare first thrown promiscuously into the hopperHin which they areseparated and fed by the feed rollers f and f one by one into the upperend of the chute I in which the coins travel down their properslide-ways 1, 2, 3 and 4 into their proper stacking tubes (Z. n and grespectively; the dimes traveling through guide-way 1 and opening d intostacking tube d; the pennies traveling through guide-way 2 and opening12' into stacking tube 1); the nickles traveling through guide-way 3 andopening 12/ into tubes drop into the barrels B of the sorting mechanismsS and fill said barrels with the predetermined number of coins.

The rotation of the cams 71 by shaft 70 swings the upper end of thelevers 76 forwardly which through links 77 idraw the slides s forwardly,separating and sorting. the coins in the barrels'B from those in thestacking tubes, until the lower end of said barrels coincide with theopenings 15 in the slideways s, whereupon the stacks of coins in saidbarrels drop through said openings and through the throats 33 into thewrapping mechanisms W between the rollers w, 'w, 'w and 10 onto theplunger head 59; the upper ends of said rollers at this time having beenspread apart to receive the coins, by the engagement of the cam slots 36with the upper journals 24 to 27 inclusive of said rollers, with theturnin of the cam disk 34 by the engagement of tie lever 79 with thedisk arm 37 upon the swinging of said lever by the cam 72. When theslide barrels B are moved from under the stacking tubes d, p, n and q,the upper plates 12 of the slides 3 pass under the lower ends of saidtubes and support the stacks of coins therein, until he slides return tonormal position and heir barrels B again rest under the stack- 1 ngtubes, whereupon a predetermined numer of the lowermost coins in saidtubes again drop into said barrels for the next sorting operation. Eachtime a slide 8 is moved forwardly and the stack of coins dropped fromits barrel, the counting mechanism is operated by the link 16 and onestack is registered on the register B.

As soon as the coins drop into the wrapping mechanisms W the levers 79are swung by'the cams 72 backwardly and the springs 38 turn the camdisks 34 clockwise; whereupon the cam grooves 36 engaging the upperjournals 24 to 27 inclusive swing the upper ends of the rollers 10, 'w,'w and 'w inwardlyagainst the coin stacktherebetween, while the lowerends of the rollers are drawn against the coin stack by the spring belt64,

i coils (see Fig. 13) while the lower and upper edges of the wrapper arerespectively crimped by the crimpers K and K a short distance over thelower face of the lowermost coin in the stack, and a short distance overthe upper face of the uppermost coin in the stack, leaving a sufficientarea of said faces of said coins exposed so that the denomination of thecoins may be seen and read (see Figs. 6 and 14). The rollers w, w, 'wand w are then spread apart by the cam 72, through lever 7 9, cam diskarm 37,

disk 34 and cam slots 36, and journals 24:

to 27 inclusive. The plunger 58 is then elevated by the cam 73 throughlever 80 and the wrapped stack of coins is elevated out of the wrappingmechanism W through throat 83 as shown in dotted lines in Fig. 6.
